SF ECIFICATiON forming part of Letters Patent No. 538,013, dated April23, 1 89 5.

' -:Application filed December 10, 1 94. Serial No. 1,311- (N m To allwhom it may concern.-

I Be it known that we, CHARLES A. CUsHMAu and JAMES F. GUTHRIE, ofSomerville, county State-of Massachusetts, have invented an Improvementin Packing-Presses,

of which the following description, in'con nection with the accompanyingdrawings, is a.

. cles are packed operation,

- tion' of a simple, compact and rapidly operspecification, like lettersand figures on the drawings representing like parts.

When bacon, hams and other similar artiinto boxes, it is desirable topack the boxes or cases as tightly as possible, not-only to thoroughlyfill them, but to also during transportation.

prevent movement or shiftingof the contents In packing-houses, presseshave beenv employed for this purpose, the be): or case. with its contents, being placed under the plunger of the press with the box coverbetween the contents and the face of the'plunger, is applied to thelatter to force the lid or cover into place, compressing the contents bysuch and the cover'is' nailed or otherwise secured in place before thepressure is removed. So far as we are aware,the presses used-for thispurpose are cumbersome, requiring the combinedstrength of several men tooperate them, and, in practice, it takes considerable time to pack eachbox or case.

This invention-has for its object the producated power-press, the pressbeing mounted upon asuitaole track so that it can be quickly moved fromone pointto another, thus ob: viating considerable handling of thepacking cases, the application ot-motive power to the press,automatically acting. to hold it stationary and rigid against the fixedabutment.

In accordance therewith our invention consists in details ofconstruction, arrangement and operation hereinafter fully described andparticularly pointed out in the claim.

Figure 1, in end-elevation, represents a A press embodying ourinvention, the plungerrod being broken off to 'a longitudinal sectionand Fig. 3, is a save space. Fig 2, is on the line at, Fig. 1; sectionaldetailon the line We have hereinshown the press as composed of a strongcylinder at having heads a and power plunger rod as rotatably a,suitably flanged and connected with the flanged ends of the cylinders bybolts 10, ill

. usual manner.

The head a is made-as a solid block and cylindrical at its outer end toreceive thereon a cap I) chambered out at b to receive easily thereinthe cylindrical end of the head a, the

wise supported, if desired, said beams, however, being adapted to form arigid abutment for the upper end of the press when in use.

The cylinder head a has a plunger-opening therein, and alsofa suitablestufiing box et -and downwardly extended guides a terminating in abearing a some distance below the head to guide the plunger-rod a whenextended. The said plunger-rod has secured thereto a suitable piston e,movable in the cylinder, and we haveshown the outer extremity of the largroove 6 and co-operating, plate c to a bearing block 6 secured bysuitable bolts, as 5, to a plunger e whereby the latter is rotatableabout the plunger-rod.

We have secured to the cylinder herein shown, as'by bolts 15, avalve-boxf, having a four-way valve f therein of usual construc-' tion,and as shown in Figs. 1 and 3, the valvebox has an inlet gand an outletand pipes h and Mopening respectively into the cylinder at its oppositeends and on opposite sides of the piston e.

As shown in Fig. .2, the plunger is retracted, and the apparatus is inposition to pack a box when broughtbeneath the plunger c and the valve fas shown in Fig.6, is turned to connect the inlet 9 with the pipe hleading to the upper end of the cylinder, the on lot or ex haust g beingconnected with t e pipe 7t forming the cylinder exhaust. If now steam,compressed air, or water under. pressure is adsecured by an annumittedto the cylinder through the pipe 7:, the

and asthepressnre of the fluid incneasesflhe' contents of the box orcompressed therein, and the cover on the box case will be powerfully canbe nailed in place before removed.

It will be noticed by an examination '2, that normally the weight ofsupported by the truck-wheels, e the rails (l, the cap I) being belowthe under surface of the beams A. The pressure of the fluid upon'the topof the piston e will ioroo it downward until the plunger meets the boxcover and further movement is resisted by the contents of the box orcase, end the 'gpresern'e of the fluid on the cylinder head a Willthentend'to lift the cylinder and its attached parts until the cap I) isbrought firmly a'gainst'the under side of the beams A, further pressurecompressing the air in the space I), and, cnnhthe pressure is of Fig.the press is ioning thereby the apparatus, The e flinie sion of morefluid alcove the piston will then force the plunger downward, theheanisA. act'- ing as a fixed abutment for the apparatus until thecontents of the box or case have been sufficiently secured in place. Assoon the cover has been secured,the valve f is turned bymechanisin to bedescribed, to connect the pipes It and g and pipes g and it", so thatthe fluid above the piston will be exhausted through the outlet 9',andwill be sdinii'ted beneath the piston through the pipe h to raise itinto normal position, and as soon this takes place, the press willsettle down by its'vreight until the wheels c again rest upon the tracks(1, it being understood that when the appamine is raised as has beendescribed, the wheels will be raised from the traclte and will remainout of contact therewith throughout the operation of pressing.

A valve. stem f is extended outwardly through the valve box, and hasfast thereon an arm f, which is pivotnlliy connected by links f and fwith handle e pivoted at f to a boss of on one of t e restingtrigoncompressed to enable the cover to he" Vere f n-nil Thehearingnli'or the JhiHgBIE' I'Od e'is out ,Fig. 2, to receive therein ahearing blooka" held 'in adj ustcd away at one side, as at a parts ofthe pa'ckinganother point as it; may: he; needed, so that onemen canoperate'the prese'with the greatest ease.

The press is very rapid and efiicient inoperetion, and steam, mien-orcompressed, air may he usedns the motive fluid-as desired or ts mostconvenient, neeted with the source of supply byLflexi'ble tubing, and bysimilar means. the exhaust may be cerried to any desired point.

it will be obvious that the press may beused in any case where itr-isdesired to compress any substance into smaller space, whether confinedin a case or box or not, for it will be evident that baled products maybe compressed preparatory to being handed or otherwise held incompressed condition.

We clainm- In a compressing or packing press, shylincler having a portat each end, a piston rcciprocablo therein, and rod end plunger,combined with a controlling valve for said ports, an internally recessedcap on and into which-the closed end of the cylinder, tightly enters asa piston to i'orm an air cushion .when moved against a fixed abut--ment, and menus to portshly-cnepend said cylinder, substantially asdescribed. 1
